VALVE.

application filed May 9, 1919. Serial No. 295,816.

To all whom it may concern:

Be it known that I, VVINFIELD S. LIVEN- soon, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference markedthereon, which form a part of this specification.

This invention relates to faucets for use on tanks or containers and particularly for that class of receptacles containing oils and the like. is to provide a tank faucet which will be inexpensive to manufacture, which will insure ease of operation and which will be so constructed that it may be temporarily looked against unauthorized use, one of the features of the invention being the provision of means for maintaining the valve difierent distances from itsseat so as to vary the effective cross sectional area of the orifice surrounded by the valve seat.

The device is particularly designed for use in connection with tank wagons and in actual practice, it has been found that those valves which only have a full opening movement and a full closing movement are objectionable for the reason that the size of the stream issuing from the tank cannot be regulated It frequently happens that the oil must be transported from the tank onthe wagon to a tank in a store or other building and the transportation is accomplished by the operator filling a metal bucket or can and carrying it to the point of distribution. In order to save time it has become the practice of the operators to hang one can upon a projection or nose on the faucet to be filling while a filled can is taken to the point of distribution and returned. This is a convenient way of saving time where the distance between the tank and the store or other building is short but where alonger carry is required, it not infrequently happens that by the time the operator gets back to the tank wagon, the filling can has overflowed.

I have provided means whereby the ad- I vantage of saving the time can be usedwith One of the objects of the invention the additional advantage that the valve can be opened different degrees so that a small stream or a large stream may be permitted to flow from the tank and this adjustment is under the control of the operator.

In the drawings, Figure l is a side elevational View of a faucet constructed in accordance with my I.

invention.

eferring now to the drawings by numerals of reference:

1 designates the valve casing which consists of a substantially T-shaped hollow casting having a threaded inlet portion 2 whereby the faucet may be screwed to a pipe or threaded projection on the tank or receptacle, the casting being provided with a downwardly projecting nozzle 3 having an outstanding bucket supporting lug or horn 4 and a terminally threaded hose receiving end 5 adapted to be closed by a cap 6, if desired. The casting is also provided with a polygonal portion 8 whereby the same may through slide, the lever being be screwed upon a support or pipe by an orslidably secured in the box 12, threaded at 13, and the casting 1, and bearing against the packing 14: about the opening 10 whereby a stufling box is provided. The slide 11 is formed with a recess 16 in which one end of the coil spring 17 is seated, the opposite end of the coil spring bearing against the guide 18 in which a valve stem 19 is slidably secured. One end of the valve stem 19 is screwed into the slide 11 and the other carries a flanged sleeve 20 which is secured thereto'by a transverse pin 21 which permits a slight rocking movement of the sleeve 20 with respect to the stem because the diametc:- of the recess 22 in sleeve 21 is slightly spring 17 is an expansion spring, it is obvious that there will be a tendency to move the slide 11 away from the guide 18 and thereby seat the valve 23. This tendency will be augmented by the pressure of oil passing through the inlet 2.

The box member 12 which constitutes the removable end of the .casting 1 is provided with outstanding flanges 26 and 27, spaced apart to boundthe lever receiving slot 28 adjacent to the pocket or slot 29 in slide 11 and these flanges 26 and 27 are provided with slightly curved transverse slots 30 and 31 to receive or seat the oppositely dis 7 posed lugs or projections 32 and 33 of the valve operating lever -a slot-engaging 34, said lever having terminal 35 which is adapted to lie within the slot 29 of the slide 11, as best shown in Fig. III.

I The lever 34 is provided with a downwardly projecting rack-engaging ,end 36. the opposite faces of which are slightly inclined to provide pawl edges to engage the segmental rack or toothed flange 37 depending from the casting 1, being carried by the removable box member 12. The slot 30 in flange 26 is slightly lower than the slot 31 in flange 27 so that the normal tendency of the lever will be tot eeter from right to left, as seen in Fig. II, to throw the end 36 into engagement with one of the teeth 38 on rack 37, there being suflicient play in the slot 28 to permit the lever to be shifted sidewise; therefore, it will be seen that the sidewise motion from left to right (Fig. II) will move the pawl end of the lever 34 out of engagement with the rack 37 and a reverse movement will throw the pawl into engagement with one of the teeth of the rack 37. For example, the removable lever 34 may be rocked in the notches 30 and 31 into the slot in the slide so that a movement of the handle from left to right (Figs. I and III) will be eflective in operating the valve the desired extentand it may be held in this position by permitting the projecting finger or pawl end 36 to engage one of the teeth 38 on the 'rack 37; therefore, the effective port area of the opening surrounded by the valve seat may be varied to a number of adjustments between'two extremes.

When it is desired to lock the valve against operation, the lever may be removed and the hasp 39 of a padlock 40 may be passed through the slots 48 and 48, as

shown in Fig. IV. When thus locked the valvecannot be opened by an unauthorized person. v

In Fig. V I have shown a slightly modified form of valve in which the rack'consists of a hinged. plate 41 secured to the casting 1 and having teeth 42, the top edge thereof to be engaged by a tooth 43 of a lever 44, in all other respects, resembling the lever 34. The hinged plate 41 is pro-- vided with a slot 45 which is adapted to fit over a staple 46 carried by the casting 1 so that the hasp of a lock may be introduced through the staple after it has passed the slot and the valve locked against operation. The valve may be also looked against operation by introducing the hasp through a transverse opening 47 which-passes through both flanges and through an opening in the slide 11 not shown. When the plate 41 is in its operative position, it stands upright, as shown in Fig. V but when it is desired to lock the valve, the plate hinges over on the hinge 48 so that the staple 46 may pass through the slot 45 in an obvious manner.

What I claim and desire to secure by Let ters-Patent is:

1. A faucet comprising a casing having a slot extending vertically through it and provided with an inlet and an outlet, a valve between the inlet and the outlet, a, spring-actuated slide for normally maintaining the valve on its seat, upstanding flanges on opposite sides of the slot and provided with seats, a. flange depending fromthe casing adjacent to the slot and having teeth, and a valve unseating lever insertible through tions to engage said seats, the lower end of said lever being engageable with the teeth on the flange.

2. A faucet comprising a casing having an inlet and an outlet, a valve in the casing, a valve actuating lever supportable by the caslng and having a projectingend extending through a slot in the casing and through a slot in the valve, and a ratchet, engageable by the projecting end of the lever.

' 3. 'A faucet comprising a casing having an inlet and an outlet, a valve between the inlet and the outlet, spring actuated means for normally maintaining the valve upon 1ts seat, a valve actuating slide having an actuating-lever -receivin'g opening normally alining with an opening in the casing, an

ture.
